POLE FOR ELECTRIC WIRES.

SPECIFICATION forming part of Letters Patent No. 449,375, dated March 31, 1891.

Application filed October 8, 1890'. Serial No. 366,969. (No model.)

overhead wires of electric railways and for similar purposes; and the invention consists of-a pole for electric wires composed of two or more an gle-pieces of iron or steel that converge from the base toward the upper end, transverse pieces or plates for connecting the angle-pieces and base plate or shoe, and an gleirons for attaching the lower ends of the converging angle-pieces to the base plate or shoe.

In the accompanying drawings, Figures 1 and 2 represent a front and a side elevation of our improved pole for electric wires, made of two converging angle-pieces. Figs. 3 and 4 are front and side elevations of a modified construction of the same. Fig. 5 is a side elevation of a pole constructed of four converging angle-pieces, and Figs. 6, 7, and 8 are horizontal sections, drawn on a larger scale, showing the connection of the angle-pieces with a base plate or shoe.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A A represent two or more angle-pieces of wrought iron or steel, which are either made straight or slightly curved, and so arranged as to converge from a shoe or base-plate B toward the top end of the pole. Forpoles of ordinary strength, two converging angle-pieces A are sufficient, while for stronger poles more than two angle-pieces may be used, as shown in Fig. 8. The angle pieces A maybe arranged in any relative position toward each other, provided that the apices of two angle-pieces are in line with the central line of the base plate or shoe B. The converging an gle-pieces A are connected either by transverse pieces or lattice-work C, as shown in Fig. 1, or by wrought or cast steel or iron plates C, as shown in Figs. 3 and 5, said pieces or plates being pivoted or bolted to the angle-pieces. The lower ends of the angle-pieces A are attached to the base plate or shoeB by anglepieces D, which are riveted to the angle-pieces A and the base-plate B, respectively, by means of bolts or rivets. The bottom plate B may be cast or made of wrought iron or steel, or of a block of wood of any suitable size and thickness.

The base plate or shoe B is set into the ground at a suitable depth below the surface of the same and the space between the anglepieces filled up with masonry or cement.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A pole for electric wires, composed of two or more angle-pieces of iron orsteel that converge from the base toward the upper end, transverse pieces or plates for connecting the angle-pieces, a base plate or shoe, and angleirons for attaching the lower ends of the converging angle-pieces to the base plate or shoe, substantially as set forth.

In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
